The difference

Ailurn vs Brilliant in practice

Brilliant Premium is about $24.99/month or $149.99/year. Lessons are click-through problems with excellent UX. The catalog is finite and editorial. There is no “build me a course on our billing system.”

Ailurn will generate a probability course if you ask, but it will not match Brilliant’s interactive widgets. For intuition in quantitative fields, Brilliant is still the specialist. For a custom path that includes Brilliant-like topics plus your job context, Ailurn can sequence the work—without the same interactivity.

Do not cancel Brilliant to save $12 if you actually use the daily problems. Do not subscribe to Brilliant hoping it will teach your company’s stack.

Brilliant is a strong fit when
